trimethylsilyl phosphite (DTMSP) with aldehydes were converted, by treatment with lithium diisopropylamide (LDA) followed by the successive alkylation and alkalinehydrolysis, to carbonyl derivatives involving aldehydes, unsymmetrical ketones, β,γ-unsaturated ketones, and carboxylic acids. β-Substituted carboxylic esters and γ-substituted lactones were prepared by use of the carbonyl addition compounds of DTMSP

β-Alkyl-substituted carboxylates were synthesized in good yields from α,β-unsaturatedaldehydes by using the 1:1 carbonyl adducts with diethyl bis (trimethylsilyl) phosphite.

Dialkyl 1-trimethylsilyloxy allylphosphonates (3a-3f) were synthesized by a one-pot reaction of trialkyl phosphite (1), carbonyl compounds (2) and trimethylchlorosilane. The procedure was carried out under very mild conditions and was very easy to conduct. The structures of (3) were confirmed by IR, (1)HNMR, P-31 NMR and MS.
